Abstract
Recently, many composite structures made of concrete and steel have been developed and various shear connectors are presented in order to increase their load carrying capacity. Among these connectors, a new type of shear connector called “perfobond shear connector” has been developed and design formulas of it are derived by experimental studies. The most popular and fundamental one is presented by Leonhardt. Although the formula of Leonhardt is widely used, it is pointed out that the applicable scope has not confirmed well. Thus, parametric analyses using 3D elasto-plastic FEM for the perfobond shear connector are performed in order to investigate appropriateness and applicable scope of them in this study. Furthermore, shear fracture behavior between rib and concrete is simulated in the analyses.
